摘要:
2022年1月8日青海门源6.9级地震中，硫磺沟铁路桥毗邻震中，出现严重震损，造成兰新高铁停运。这是较为典型的近断层高铁桥震害。为全面记录和保存震害信息，采用无人机倾斜摄影测量构建了铁路桥的精细震害三维模型。基于该模型对铁路桥的跨度、主梁纵向、横向位移和横向倾斜转角进行了测量估计。结果表明模型尺寸基本符合实际；桥墩未出现明显位移或倾斜；主梁纵向位移呈现南侧主梁北移，北侧主梁南移，可能源于垂直于地震破裂带方向上的脉冲作用及桥台约束；主梁横向侧移呈现南侧多数主梁向西移动，北侧少数主梁向东移动，可能源于平行于地震破裂带方向的往复运动和地震行波效应；主梁横向倾角分布显示，所有主梁均向东倾斜，南侧主梁倾斜幅度较大，北侧主梁倾斜幅度较小，源于横向侧移致使主梁底端一侧滑落至垫块以外，以及轨道对主梁相对变形起到的约束作用。三维模型和位移数据可为高速铁路桥震害分析、仿真模拟提供技术支撑。
Abstract:
Liuhuanggou Railway Bridge was seriously damaged in Qinghai Menyuan M6.9 earthquake on January 8,2022,caused traffic disruption of the Lanxin high speed railway. It is a typical near folt damage case of simply supported beam high speed Railway Bridge. In order to record the seismic damage,accurated 3D model of the damaged bridge is built up by oblique aerial photography. The bridge span,longitudinal displacement, transversal drift and the lateral inclination of every beam are measured and calculated according to the 3D model. It shows that the 3D model is in well agreement with the bridge. No obvious inclination is found in piers. Longitudinal displacement distribution of the girders is as follows:the south girders moved north and the north girders moved south,which can be attributed to the combination of near-fault pulse ground motion and the abutment restraint. Transversal drifts of the girders are presented:most girders in south part moved west and few girders in north part moved east,which can be attributed to the reciprocating motion parallel to the surface rupture direction and the traveling wave effect of the ground motion. The girders inclinations shows that all the girders inclines eastward,girders of south part tilted more steeply,which is supposed causing by the transversal drifts and the constraints of the tracks. It can be reference to the seismic evaluation and numerical simulation analysis of the bridges.
